Preferably, the driving wheel and the front wheel have the same size, and a mudguard of the driving wheel is further arranged on the rear pedal.

Preferably, a vertical pipe is connected in the head pipe in a sliding manner, and a handle is arranged at the top of the vertical pipe.

Preferably, a battery is mounted to a rear portion of the head pipe, and the battery supplies electric power to the driving wheel.

Preferably, the distance between the front group of the dragging wheels and the rear group of the dragging wheels is 10-15 cm.

Compared with the prior art, the invention has the beneficial effects that: on the premise of ensuring the folding strength and convenient use, the invention adds two towing wheels, aiming at being capable of standing up and towing under the supporting action of the towing wheels and the front wheels after being folded;

this electric scooter is folding back than traditional scooter volume 45% less, and area is 65% (size 35CM 15CM) less, folding back high 55CM, under the prerequisite that does not influence the scooter quality of traveling, furthest has reduced folding size for this electric scooter no matter is at subway public transit or elevator, can all carry under the condition that does not influence anyone and drag the line.

FIG. 3 is a schematic view of the configuration of the invention with the tow wheel not installed;

fig. 4 is a schematic structural view after the folding of the present invention.

In the figure: the bicycle comprises a front pedal 1, a hinge 2, a rear pedal 3, a driving wheel 4, a mudguard 5, a front wheel 6, a front fork 7, a towing wheel 8, a sleeve 9, a lock nut 10, threads 11, a battery 12, a head pipe 13, a notch 14, a preformed hole 15, a pin shaft 16, a stand pipe 17 and a handle 18.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: the utility model provides an electric scooter, includes front fork 7, anterior footboard 1 and rear portion footboard 3, install drive wheel 4 on the footboard of rear portion 3, movable mounting has front wheel 6 between the front fork 7, connect through hinge 2 between anterior footboard 1 and the footboard of rear portion 3, behind the front end inside stretching out of front fork 7 top via anterior footboard 1, through 16 swing joint in the lower extreme of head pipe 13 of round pin axle, the head pipe 13 lower extreme has lock nut 10 through the screw thread 11 spiro union on it, sleeve pipe 9 has been cup jointed to head pipe 13 lower extreme, head pipe 13 lower extreme front side is equipped with the preformed hole 15 that is used for the installation to drag the capable shaft, two sets of dragging wheels 8 around dragging the capable shaft swing joint, sleeve pipe 9 lower extreme front side is equipped with the breach 14 for dragging capable shaft installation preformed space.

Specifically, the driving wheel 4 and the front wheel 6 are identical in size, and the rear pedal 3 is further provided with a mudguard 5 of the driving wheel 4.

Specifically, a vertical pipe 17 is slidably connected in the head pipe 13, and a handle 18 is arranged at the top of the vertical pipe 17.

Specifically, a battery 12 is mounted at the rear of the head pipe 13, and the battery 12 supplies electric power to the drive wheel 4.

Specifically, the distance between the front and rear groups of dragging wheels 8 is 10-15 cm.

Specifically, when the electric scooter needs to be unfolded, the rear pedal 3 is rotated by taking the hinge 2 as a circle center until the upper end surface of the rear pedal 3 is flush with the upper end surface of the front pedal 1, then the head pipe 13 is rotated by taking the pin shaft 16 as a circle center until the head pipe 13 and the front fork 7 are positioned on the same straight line, and finally the sleeve 9 is locked by the locking nut 10 until the sleeve 9 sleeves the joint of the head pipe 13 and the front fork 7;
