Description of the Related Art As an electric riding tricycle, a rear wheel is provided on both outer sides of a rear portion below a substantially rectangular traveling frame, a vehicle height having a front wheel mounted on a front center, or a front central portion of the traveling frame. There is a case in which the entire traveling frame whose front wheel is narrowed by accommodating a front wheel in a convex front wheel accommodating portion formed in the above is lowered, and a rear wheel is exposed on both outer sides of a rear portion of the traveling frame and axle-mounted. A steering wheel and a seat are arranged before and after the traveling frame, and the direction of the front wheels can be changed by operating the steering wheel.

具合があった。Therefore, according to this kind of electric riding tricycle, when a disabled person or an elderly person drives while sitting on a seat and grasping a steering wheel, a constant angle at which the body loses lateral stability is obtained. Even if the vehicle is tilted as described above, since the entire running frame is high or the width is narrow even if the running frame is low, both sides of the central portion do not contact the ground, so that there is a problem that the vehicle easily falls over.

For this reason, the running frame is made as narrow as possible as a necessary frame by the pipe material. Therefore, it can not be said that there is enough space for getting on and off the foot
The risk of falling increases.

For the traveling frame that arranges the steering wheel and seat in the section and the rear bending section,
In an electric riding tricycle having a front wheel linked to the steering wheel at the center lower part of the front curving part and a rear wheel at the outer lower part on both sides of the rear curving part, lower the getting on and off part to near the plane passing through each axle of the front and rear wheels. At the same time, it gradually protrudes outward from the end of the running frame to the left and right outward from the rear part of the front curved part and the getting on and off part, and the top surface is almost flat with the top surface of the running frame to prevent tipping over An object of the present invention is to provide a frame structure of an electric riding tricycle characterized by providing an overhang portion.

In other words, it gradually protrudes outward as it goes from the end face of the running frame toward the rear from the end face of the running frame to both the left and right sides between the rear part of the front curving portion and the getting on / off portion, and the top surface is substantially flat with the top surface of the running frame. Since the overhang portion is provided, the overturn prevention overhang portion is provided only at a necessary portion, and does not unnecessarily increase the weight. Further, the overturn prevention overhanging portion also plays a role of widening the narrow getting on / off portion.

Things. That is, the traveling frame 1
The main frame is formed by attaching cross beams 1b, 1c, and 1d to the front, center, and rear ends of a U-shaped frame 1a formed by bending a rod material such as a square pipe or a round pipe into a substantially U-shape. The front end side and the rear end side of the main frame are respectively bent upward to form a front bent portion 9a and a rear bent portion 9b, and between the front end of the front bent portion 9a and the front cross beam 1b. A protruding handle support base 6 for fixing the handle tube 6a is protruded,
Further, a pair of L-shaped seat supports 7 are attached from the center of the main frame (central cross beam 1c) to the rear end of the rear curved portion 9b (rear cross beam 1d). A flat support member 7a having a chevron 7b is fixed, and a flat plate is attached to a horizontal portion between the rear end of the front curving portion 9a and the central cross beam 1c to form a flat getting on / off portion 9c. It is.

The overturn prevention overhanging portion 8 made of the same bar is gradually projected outwardly from the end face of the traveling frame 1 toward both sides toward c. As shown in FIG. 2, the upper surface of the overturn prevention overhang portion 8 is connected to the traveling frame 1, that is, the rear portion of the front bending portion 9 a and the getting on / off portion 9 c
Are set substantially flush with the upper surface of the. Furthermore, in order to eliminate the danger of an object or the like directly touching the rear wheel 5, and to prevent the rear wheel 5 from being caught on an object during turning, the rear curving portion 9 is provided.
b, the rear wheels 5 outward from the end face of the traveling frame 1
The protection and mud removal frame 10 projecting to the outside is extended so as to cover the front upper part of the rear wheel 5.

It is preferable to extend outwardly from the XX line and the YY line connecting the respective rear wheels, and to the width of both rear wheels up to about five. Therefore, as a specific configuration of the overturn prevention overhanging portion 8, as shown in FIG. 1, the overhanging overhanging portion 8 is extended up to a line connecting both rear portions of the front bending portion 9 a and both outer corner portions of the front end of the protection and mud removal frame 10. Shape. Also, the heights of the entry / exit portion 9c and the overturn prevention overhanging portion 8 connected thereto are reduced to a height connecting the axles of the front wheel 4 and the rear wheel 5 to each other. Note that the overhanging protruding portion 8 and the protective and mud removing frame 10 are covered with a thin cover material so as to be invisible (see FIGS. 3 and 4).

The start switch 12, the forward / reverse changeover switch 13 and the accelerator lever 1 are attached.
By appropriately operating the motor 4, the power of the DC motor 15 is transmitted to the rear wheel 5 via the transmission 16 and is driven forward and backward.

Since the overturn prevention overhanging portion is provided in a necessary portion in a specific shape, the weight does not increase unnecessarily. Further, since the upper surface of the overturn prevention overhanging portion is set to be substantially flush with the upper surface of the getting on / off portion or the like, it does not hinder getting on / off and also serves to widen the narrow getting on / off portion.
