Description

Electric Kickboard {ELECTRIC KICKBOARD}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an electric kickboard, and more particularly, to an electric kickboard capable of safely operating as smart mobility and performing various riding through coupling.

Generally, personal moving means using electric power include electric wheel, electric bicycle, electric kickboard, electric bike and the like.

Although these devices have different lengths in terms of product type, price, portability, and convenience, most of them are used for convenient transportation or leisure purposes.

The electric kickboard of the prior art is constructed in a basic form of a kickboard capable of steering by a steering wheel and can be driven by an electric force by attaching a power-related device to the body or wheel of the kickboard.

Such conventional electric kickboards have an average speed of about 25 Km / h. In some high-grade types, they have a speed of 40 to 60 Km / h, and can exhibit their backing ability even in some slope sections.

However, the prior art motorized kickboards can run at significantly higher speeds than a typical user's walking speed, so that the protrusions on the front ground, or in particular, the unexpected feature during night driving, It is very easy for safety accidents to occur.

In addition, the electric kickboard of the related art is prevented from being driven even when the motor-driven lever (for example, an acceleration lever) is pulled when the electric kickboard or the electric bicycle is in a stopped state, for safety reasons. Therefore, the user, that is, the occupant of the electric kickboard, puts the one foot on the electric kickboard, the other foot on the ground, and then applies the force to the other foot of the ground to push the electric kickboard by the user's own force, When activated, the electric kickboard is driven. However, such a driving method may be difficult to use in a stopped state in the direction of raising the incline from the ramp, and may cause a safety accident in the descending direction of the incline.

In addition, the electric kickboard of the prior art is manufactured in the form of a single ride, or when two persons are riding, it is very dangerous or can not enjoy riding properly due to the speed reduction.

In addition, the prior art electric kickboards may not be wobbled or unbalanced in the width direction of the kickboard, i.e., in the lateral direction due to premature operation, collision with the front ground surface protrusion, manipulation of an excessive or immature steering wheel, The weight of the electric kickboard is heavier than that of a general lightweight bicycle. Therefore, it is difficult to recover the restoring force due to the operation of the steering wheel rapidly, leading to a rollover accident. There is a situation.

The lower protrusion height of the protector 340 may be a wedge shape or a triangle block shape that is relatively lower than the downward protrusion height of the side wheel 300 and may be formed of an engineering plastic material or an elastic material having high durability. In other words, the protector 340 is a victim installed in a front position of the side wheel 300, so that the side wheel 300 can be securely protected from the contact with the road- There is an advantage to be able to do. That is, the protector 340 is detachably attached.

And a central controller for controlling operation of the traveling motor or the light corresponding to an input signal of the sensor unit;
A battery for supplying electric power to the traveling motor and the control device; And
And a side wheel motor driving unit connected to the central controller of the control unit for forward or reverse rotation of the side wheels with the side wheel motor in response to the lateral reference slope sensed by the tilt sensor Electric kickboard.
The method according to claim 1,
Wherein the central controller of the control device receives the measurement value of the tilt angle of the board body in the longitudinal direction from the tilt sensor and guides the user to the cruise function and connects to the central controller so as to correspond to the cruise range speed value set in accordance with the guide The amount of output of the traveling motor is increased or decreased in proportion to the measured value of the tilt angle through the traveling motor drive unit or the braking amount of the brake is increased or decreased through the brake driving unit connected to the central controller to maintain the speed in the slope The electric kickboard is characterized by.
3. The method of claim 2,
Wherein the sensor unit further comprises an illuminance sensor,
The central controller adjusts the ambient brightness corresponding to the brightness detection value around the moving path during the nighttime movement input from the illuminance sensor. When the ambient brightness is dark through the dimming driving unit connected to the central controller, And controls the brightness of the light to be darker than a preset value when the surrounding brightness is bright.
The method of claim 3,
Wherein the sensor unit further comprises a switch,
And the central controller controls the laser irradiator through a beam driving unit connected to the central controller in response to the on / off signal of the switch, so as to move the laser beam from the laser irradiator toward a ground surface relatively farther than the irradiation distance of the illumination light, And a laser beam of a mesh structure pattern is irradiated.
5. The method of claim 4,
The sensor unit further includes an acceleration sensor or a gyro sensor interlocked with the tilt sensor so that the user performs a kick and go function to start toward the slant direction after the electric kickboard is stopped at the ramp,
The central controller checks the operating state or tilt posture signal of the electric kickboard according to the kick through the tilt sensor, the acceleration sensor, or the gyro sensor, and adds or subtracts a predetermined kick range velocity value corresponding to the tilt posture signal And controls the traveling motor driving unit and the brake driving unit such that the electric kickboard moves at a speed corresponding to the addition or subtraction.
The method according to claim 1,
Wherein the side wheel is mounted on the bottom surface of the board body and is supported by a damper that absorbs impact.
The method according to claim 6,
Wherein,
And a protector provided on a bottom surface of the board body with respect to a front position of the side wheel. delete delete delete delete delete delete
