DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a small electric four-wheeled vehicle that can be used for an electric wheelchair, a golf cart and the like.

[0002]

2. Description of the Related Art A small electric four-wheeled vehicle of this kind is disclosed in
No. 258090, JP-A-10-6998 and the like.

[0003]

SUMMARY OF THE INVENTION The present invention is directed to a small electric four-wheeled vehicle, in which the entire body of the vehicle is made compact and the foot of the occupant is made as wide as possible.

[0004]

The left and right front wheels 2, 2 steered by a steering wheel 1 and the left and right rear wheels 3, 3 forming driving wheels.
A single seat 5 is mounted on the left and right central portions of a chassis 4 including: and the chassis 4 between the seat 5 and the front handle 1 is covered with a resin plate or the like to form a step 6, and Steps of a small electric four-wheeled vehicle in which auxiliary steps 8, 8 extending left and right from both sides of the front part of step 6 on the rear surfaces of fenders 7, 7 covering front wheels 2, 2 are superposed.

[0005]

As described above, according to the present invention, the step 6 is extended widely by the auxiliary steps 8, 8 extending from the front sides of the step 6 to the rear surfaces of the fenders 7, 7, and the vehicle body is enlarged. It is possible to steer without tiredness by widening the feet without performing.

Embodiments of the present invention will be described below with reference to the accompanying drawings. The chassis 4 is formed of a pipe frame, and the support pipes 10 and 10 are respectively welded and fixed at positions slightly behind the middle in the front-rear direction of the left and right side frames 9 and 9 and are slightly inclined rearward to be positioned at the top. Sheet 5 is attached. 11 is a backrest and 12 is an armrest.
A pair of left and right front wheels 2, 2 is provided at the front of the chassis 4,
The front wheels 2, 2 are held at both ends of a swing arm 13 that can swing left and right about the center of the chassis 4, and are formed in a so-called center pivot system so as to cope with road surface irregularities.
Further, the front wheels 2 are turned around a king pin 14 via a steering mechanism (not shown) by turning operation of the steering wheel 1 so as to be steerable. Reference numeral 15 denotes an operation box, which is provided at the upper center of the handle 1 and has an operation device such as an accelerator lever 16. Also, shaft 1 of handle 1
7 is a two-piece structure in consideration of strength and design.
The handle 1 is connected to a U-shaped lower end of the handle 1 via a rotation adjusting tool 18. 19 is a front basket, and 20 is a headlight. The rear wheels 3, 3 are driven by a drive mechanism or the like (not shown) including a motor, a battery, and the like, and are covered by an integrated rear cover 21. Reference numeral 22 denotes a front cover which covers the above-described front wheel steering mechanism, the lower portion of the handle shaft 17, and the like, and the left and right sides thereof are integrally formed with the fenders 7, 7 of the front wheels 2, 2. Behind the fenders 7,7, a paragraph 23,
23 are formed over the entire width. The upper part of the chassis 4 between the seat 5 and the front handle 1 is covered with a resin plate to form a flat-floor step 6 for a passenger. In addition, the front part of this step 6 is a front step 2 which is inclined and extended upward and forward.
4 and auxiliary steps 8, 8 extending to the left and right from both sides of the front step 24 and overlapping the stepping parts 23, 23 on the rear side of the fenders 7, 7 described above. Since the auxiliary step 8 is located slightly higher than the front step 24, the gap between the auxiliary steps 8 is continuously formed by the inclined surfaces 25, 25. Folded edges 26, 26 are formed on the rear surface of the fender 7 and the outer ends of the overlapped portion of the auxiliary step 8, respectively, and both are connected by fasteners 27 such as bolts. 2
Reference numeral 8 denotes a step cover, which is formed of a rubber plate so as to have an anti-slip function and a cushioning function, and is provided on the step 6 excluding the auxiliary steps 8 and 8. The occupant sitting on the seat 5 operates by operating the accelerator lever 16 provided on the operation box 15 while adjusting the directions of the left and right front wheels 2 by operating the steering wheel 1.
The front step 24 extends to a position close to the front side, and the auxiliary steps 8, 8 extend from both sides of the front step 24 to the rear surfaces of the left and right fenders 7, 7, so that the width direction together with the front side is increased. Step 6 is extended widely so that the feet can be widened and the tires can be operated without fatigue without increasing the overall length of the vehicle body. Further, since the auxiliary steps 8, 8 are formed by superimposing on the rear surfaces of the fenders 7, 7 from both sides of the front step 24, the auxiliary steps 8, 8 have a simple structure and sufficient strength. The back side of the auxiliary step 8 may be further reinforced by a frame or the like. Further, since the rear surfaces of the fenders 7, 7 are superposed by the auxiliary steps 8, 8, a large area of the fenders 7, 7 is provided.
The change of the material and color of the rear side 7 can be easily performed by using the auxiliary steps 8 and 8.
