Abstract

A foldable and portable electric vehicle for the transport of a single person comprises a foldable chassis with a support plate, a folding system for folding the chassis, a front driving wheel, a rear wheel, a foldable handlebar, an integrated system of command, control, monitoring and signaling, a mechanical brake on the rear wheel, a suspension on the rear wheel and a suspension on the front wheel, and a steering column.

Claims

1. A foldable and portable electric vehicle comprising:

a folding chassis with a support plate;

a folding system for the chassis;

a driving wheel in the front of the vehicle;

a rear wheel in the rear of the vehicle;

foldable handlebars;

an integrated command, control, monitoring and signaling system;

a mechanical brake on the rear wheel;

a rear wheel suspension for the rear wheel of the vehicle;

a front wheel suspension for the front wheel of the vehicle; and

a steering column for the vehicle.

2. A foldable and portable electric vehicle according to claim 1 wherein vehicle dimensions are reduced for storage or transport by having each of the handlebars comprise:

a first planar rotation body fixed to the steering column by a first slidably mounted bolt;

a second planar rotation body around the first bolt;

said handlebar being slidably mounted on the first planar rotation body and on the second planar rotation body and being provided with a rubber sleeve so that when a second bolt is pushed, there is allowance for the handlebar to slide outwardly in the direction of a tensioning spring and turning the handlebar vertically at an angle of 90°

to ensure stability of the handlebars in the folded position.

3. A foldable and portable electric vehicle according to claim 2, wherein the folding system of the chassis comprises a lever which rotates around the first bolt to train a third bolt under the action of a traction spring, unlocking the two components of the chassis that can be rotated to achieve its folding, whereby vehicle dimensions are reduced for storage or transport.

4. A foldable and portable electric vehicle according to to claim 1, wherein folding is initiated in a first stage of a folding process, the handlebars are folded in a second stage, the chassis is folded in a third stage, and the folding process is ended in a fourth stage.

5. A foldable and portable electric vehicle according to claim 1, wherein the integrated command, control, monitoring and signaling system further comprises increasing electric vehicle reliability by a control display unit mounted in a housing with an acceleration throttle, a braking throttle, a board containing an on/off button, a button for lights, a button for setting a clock, a headlight with low power consumption, a horn, a button for the horn, a unit which communicates with a main board that contains a microcontroller, sensors and a power circuit for supplying power to a DC brushless motor from an accumulator when the electric vehicle is accelerating or when the electric vehicle is braking, the same motor working as a generator, whereby kinetic energy is sent to the accumulator.

6. A foldable and portable electric vehicle according to claim 1, wherein the driving wheel is built like a brushless electric machine that operates as a DC electric motor during acceleration or as an electric generator during deceleration, and whose tubular shaft is fixed to the chassis and whose outside is fitted with a rubber tire.

7. A method for operating a foldable and portable electric vehicle according to claim 1, wherein the method comprises in a first stage, initiating the process, in a second stage, reading the status of the hard equipment, in a third stage, checking the status of the equipment, in a fourth stage, displaying battery charging status and current speed and time, in a fifth stage, pressing the acceleration throttle, in a sixth stage, checking vehicle starting, in a seventh stage, checking for need of a braking throttle, in an eight stage, pressing the brake throttle, in a ninth stage, checking for a stopped vehicle, in a tenth stage, continuing braking, in an eleventh stage, checking an emergency stop, in a twelfth stage, pushing the emergency brake, and in a thirteenth stage, stopping the electric vehicle.

8. A foldable and portable electric vehicle according to claim 1, wherein the foldable and portable electric vehicle provides integrated command, control, monitoring and signaling by increasing electric vehicle reliability, and includes a control display unit mounted in a housing with an acceleration throttle, a braking throttle, a board containing an on/off button, a button for lights, a button for a horn, a button for setting a clock, a headlight with low power consumption, a horn, a unit which communicates with a main board that contains a microcontroller, sensors and a power circuit for supplying power to a DC brushless motor from an accumulator when the electric vehicle is accelerating or during the braking operation, the same motor works as a generator and kinetic energy is sent to the accumulator.
