DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an integrated electric unit for a small vehicle in which electric components provided near a handlebar of a small vehicle such as a motorcycle or a three-wheeled vehicle are integrated.

[0002]

2. Description of the Related Art FIG. 4 is an exploded perspective view of a handlebar of a general scooter type vehicle. As shown in this figure, a handlebar 101 is supported from below by a handlebar post 102, and components such as a grip end 103 and a brake lever 104 are fixed to the handlebar 101.

[0003] Such a handlebar 101 is covered from the front and rear by a rear cover member 105 and a front cover member 106 made of synthetic resin. First, a rear cover member 105 is provided with screw fastening portions 107 provided on the left and right of the handlebar 101 and a rear bracket 108 provided on the rear portion of the handlebar post 102.
The front cover member 106 is fitted into the rear cover member 105 and fixed using both screwing. The front cover member 106 further includes a handlebar post 102
It is also screwed to a front bracket 109 provided at the front of the vehicle.

A headlight 111 is screwed into the front cover member 106 from the inside, and direction indicator lights 112 are provided on both left and right sides of the headlight 111. On the other hand, an instrument panel 113 is screwed to the rear cover member 105 from below. The instrument panel is provided with a speedometer 114 and a direction indication confirmation lamp 115, and has several built-in light bulbs for illuminating the dial of the speedometer at night and turning on the direction indication confirmation lamp. .

[0005]

However, since the headlight 111, the turn signal lamp 112, and the instrument panel 113 are provided around the handlebar 101 in an independent manner as described above, the surroundings of the handlebar 101 Since the number of electrical components is increased, assemblability is poor, and a mold for resin-molding the case and covers of each electrical component is separately required, so that the cost of the mold is extremely high.

Further, since there are many joints between each of the electrical components and the rear cover member 105 and the front cover member 106, it is difficult to obtain the joint accuracy. There is a concern that the appearance will be reduced and the appearance will be reduced.

Further, in addition to the light bulbs of the headlight 111 and the turn signal lamp 112, several light bulbs built in the instrument panel 113 are required as described above, so that the total number of light bulbs increases and wiring becomes complicated. In addition, there is a problem that the maintainability is reduced due to an increase in power consumption and an increase in the frequency of bulb replacement.

SUMMARY OF THE INVENTION The present invention has been made to solve these problems. The number of electric components around the handlebar is reduced to improve the assemblability and reduce the number of resin molding dies. The joint between the cover member that covers the bar and the electrical component is reduced to improve the appearance, and the number of bulbs in the electrical component is reduced to simplify wiring, improve maintenance, and reduce power consumption. It is an object of the present invention to provide an integrated electrical unit for a small vehicle that can perform the operation.

[0009]

The dial 55 is made of a material that allows light to pass therethrough, and has irregularities formed on its back surface to change the angle of light upward. The light penetrates upward through the protective cover 47 and reaches the occupant's eyes. Therefore, the occupant can check the dial 55 even at night. Thus, the light source bulb 51 of the headlight 28 is commonly used as a light source bulb that illuminates the dial 55 of the instrument panel 30.

On the other hand, a light source bulb 61 is disposed in the base case 42 of the direction indicator lamp 29. This light source bulb 61 includes
For example, a yellow or orange light bulb is used. The lens 46 of the direction indicator lamp 29 and the lens of the direction indicator confirmation lamp 38
48 is colored translucent yellow or orange, and the light source bulb 61
May be used.

When the light source bulb 61 is turned on, the light is transmitted to the lens 46 of the direction indicator lamp 29 and the lens 48 of the direction indicator confirmation lamp 38.
And the direction indicator lamp 29 and the direction indicator confirmation lamp 38 are simultaneously turned on. As described above, the light source bulb 61 is a direction indicator lamp.
It is shared by 29 and direction indication confirmation lamp 38.

The integrated base case 39 of the integrated electrical unit 34 is provided with a plurality of fixing portions for fixing the front cover member 32 and the rear cover member 33 covering the handlebar 5.

As shown in FIG. 3 (A), at the rear of the base case 43 of the instrument panel 30, for example, a projecting strip-shaped fixing portion 62 extending downward.
Are integrally formed, and a rear cover member is
The 33 mounting bosses 63 are fastened with screws 64.

Also, as shown in FIG.
The base case 42 of the 29 has integrally formed protruding piece-shaped fixing portions 65 and 66 which also extend downward, and a clip-shaped nut 67 provided on the fixing portion 65 is attached to the mounting boss of the front cover member 32. 68 is fastened with screws 69. A mounting boss 70 of the rear cover member 33 is fastened to the fixing portion 66 with a screw 71.
A fitting part is provided on the periphery of the front cover member 32 and the rear cover member 33.
72 are formed, and both cover members 32 and 33 are fitted to each other.

As shown in FIG. 3A, fastening portions 73 and 74 are formed on the front cover member 32 and the rear cover member 33, respectively, and the fastening portions 73 and 74 of the front cover member 32 are formed. Is fixed to the front bracket 75 of the handlebar post 6 with screws 76, and the fastening portion 74 of the rear cover member 33 is fixed to the rear bracket 77 of the handlebar post 6 with screws 78.
