The publication No. 0-0229084 describes an electric skateboard that is operated by the rotational force of a first motor by mounting the first motor on a skateboard.

Korean patent application laid-open No. 2003-006503 describes a skateboard for performing forward and steering using a driving footrest and a steering pedal.

The prior art as described above has an inconvenience of being actuated by pulling with a hand at the time of actuation, and a rotation radius of the front wheel is not wide, so that a sense of speed and a sense of pleasure cannot be enjoyed during actuation and rotation, so that there is no exercise function.

Also, in order to rotate left or right, a general skateboard must move the center of gravity to the left or right side of the skateboard and then press the left or right side of the skateboard, so that during normal driving, the pedals of the skateboard must move left or right to maintain directional balance, and the pedals must be deeply pressed left or right, and thus it is more difficult to change the direction.

In addition, since the direction is changed by drawing a large parabola, it is impossible to change the direction quickly, and if the condition of the road is not uniform, the board may bounce and become more difficult to balance. Therefore, it is difficult to learn the existing board and the accident rate is also high.

Referring to fig. 1 to 11, the electric scooter of the present invention facilitates riding without moving the center of gravity to the left and right in the conventional scooter, and is composed of a controller 10, a board body 20, a front wheel portion 30, a rear wheel portion 40, a first motor 60, a second motor 70, and a control device 80, so that a rider can maintain a desired angle and speed of the rider when switching between left and right.

As shown in fig. 1 to 9, the controller 10 is formed of a housing in which a handle portion 12 is formed so that a user can hold and use, and an acceleration sensor and a gyro sensor are installed inside the controller 10, and by measuring acceleration and angular velocity, it is possible to recognize the exact position and state of the three-dimensional controller 10, thereby precisely controlling the movement of the electric scooter by a rider's desired command.

At this time, the sensor unit 11 is installed at the front side of the inside of the controller 10, and the sensor unit 11 may use an acceleration sensor, a gyro sensor, an inclination sensor, etc., may use any one of X, Y, Z axes, or may use more than one axis.

Here, as shown in fig. 5, the acceleration sensor detects a change in motion in the X, Y, Z directions and receives the distributed raw data. Then, a microprocessor provided with an acceleration and rotation axis so that the control device can recognize that the rider is to accelerate and rotate, and then processes/processes the output data into data that can be processed by the control device (microcomputer). Then, the microcomputer performs acceleration and rotation according to the input value. At this time, when the controller 10 is dropped or placed on the floor, the acceleration and rotation values are corrected so that the controller 10 does not operate.

Thus, in the case where the controller 10 is dropped, the battery is mounted on the handle portion of the controller 10 so that the heavy battery portion faces downward, thereby executing the stop command.

Further, as shown in fig. 5, the gyro sensor detects a change in direction of three axes of X, Y, and Z, and receives the distributed raw data. And processes the output data into data that can be processed by the microcomputer.

In addition, when the data of the acceleration sensor and the gyro sensor are suddenly changed, the microcomputer cuts off the power to the scooter and stops the first motor and the second motor because the rider drops the controller 10 or performs a sudden control operation.

On the other hand, as shown in fig. 3 to 5, the scooter is moved forward or stopped when the controller 10 is raised or lowered while being directed upward or downward by the sensor unit 11 installed inside, and in the present invention, the scooter is advanced when the controller 10 is lowered and set to stop when the controller 10 is raised upward, but it may be set to operate in reverse. In addition, the controller 10 stops when rising upward, but may change to a reverse function instead of stopping.

And, when the left side of the controller 10 is rotated leftward while being directed to the left side, the scooter is rotated leftward, and when the right side of the controller 10 is rotated rightward while being directed to the right side, the scooter is turned rightward.

That is, when the scooter is rotated to the left, the left side of the controller 10 is rotated to the left side with the left side directed to the left side, and only the wrist is rotated by rotating the controller 10 to the left side while maintaining the traveling angle thereof, and when the scooter is rotated to the right side, the right side of the controller 10 is rotated to the right side, and when the driving angle of the controller 10 is maintained, the wrist only needs to be rotated in the correct direction.

In addition, the forward movement of the scooter is adjusted step by step according to the rising or lowering angle of the controller 10, and the stopping speed of the scooter is adjusted step by step according to the rising or lowering angle of the controller 10, and the switching of the left and right directions of the scooter is adjusted step by step according to the angle of the left or right rotation of the controller 10.

Meanwhile, a plurality of switches are installed in the controller 10 to select various riding modes, and in the present invention, the controller is composed of a first switch 13, a second switch 14, a third switch 15 and a reverse switch 16.

The riding mode when the first switch 13 is pressed is a drifting mode, and as shown in fig. 6, the front wheel portion 30 and the rear wheel portion 40 operate in different directions to cause the scooter to drift. At this time, when the controller 10 is rotated leftward while the first switch 13 is pressed, the front wheel part 30 moves leftward and the rear wheel part 40 moves rightward, thereby drifting leftward, and when the controller 10 is rotated rightward while the first switch 13 is pressed, the front wheel part 30 moves rightward and the rear wheel part 40 moves leftward, thereby drifting rightward, and by a drift speed and a direction change command, a drift speed can be controlled, and drift angles of the front and rear wheels are the same, and drift angles of the front and rear wheels can be controlled differently, and a drift angle can be controlled according to a speed of the scooter.

The riding mode when the second switch 14 is pressed is a sliding mode, and as shown in fig. 7, the front wheel portion 30 and the rear wheel portion 40 are operated in the same direction, so that the scooter slides. At this time, when the controller 10 is rotated leftward while the second switch 14 is pressed, the front wheel part 30 and the rear wheel part 40 are equally switched leftward and slide, when the controller 10 is rotated rightward while the second switch 14 is pressed, the front wheel part 30 and the rear wheel part 40 are equally switched rightward and slide, a sliding speed control and a sliding angle are controlled by the sliding speed and direction change command, sliding angles of the front wheel part 30 and the rear wheel part 40 may be differently controlled, and a sliding angle according to a speed of the scooter may also be controlled.

When the riding mode when the first switch 13 and the second switch 14 are pressed simultaneously is the rotation mode, as shown in fig. 8, when the front portion of the scooter is lifted, the pair of rear wheel portions 40 rotate in different directions, thereby rotating the scooter into position.

At this time, when the front of the scooter is lifted and the controller 10 is rotated to the left while the first switch 13 and the second switch 14 are simultaneously pressed, the left wheel is reversely rotated and the right wheel is rotated forward in the pair of rear wheel portions 40, so that the scooter is rotated to the left, and when the scooter is operated, the right wheel is rotated forward and the left wheel is rotated to the left without cutting off the power. In this case, the rotation speed may be controlled according to the rotation speed and the rotation instruction, and may also be controlled according to the speed of the scooter.

And, when the front of the scooter is lifted and the controller 10 presses the first switch 13 and the second switch 14 while rotating to the right, the left wheel of the pair of rear wheels 40 rotates forward and the right wheel rotates in reverse, the scooter rotates to the right, and when the scooter operates, the left wheel rotates forward and the right wheel turns off the power and does not rotate while rotating to the right. In this case, the rotation speed may be controlled according to the rotation speed and the rotation instruction, and may also be controlled according to the speed of the scooter.

The riding mode when the third switch 15 is pressed is a hard drift mode, and when the third switch 15 is pressed while the scooter changes direction to the left or right as shown in fig. 9, the rear wheel portion 40 stops and the scooter slides in the direction of the direction change and performs hard driving.

At this time, the front wheel portion 30 is rotated to the left side in order to make the hard drift to the left when the scooter is operated, and then the third switch 15 is immediately pressed to stop the rear wheel portion 40 so that the rear wheel portion strongly drifts to the left when sliding, and the front wheel portion 30 is rotated to the right in order to make the rear wheel portion 40 stop when the scooter is operated and the third switch 15 is immediately pressed to make the rear wheel portion 40 strongly drift to the right when sliding. In this case, the third switch 15 immediately stops the second motor 70 of the rear wheel portion 40, which may be referred to as a function similar to a hand brake of the vehicle.

When the reverse switch 16 is pressed, in the riding mode, in order to cause the scooter to run in reverse, the front wheel portion 30 and the rear wheel portion 40 rotate in reverse, that is, the front wheel portion 30 and the rear wheel portion 40 rotate in reverse, and the scooter is caused to run in reverse. At this time, when the controller 10 is rotated leftward and rightward while the reverse switch 16 is pressed, the scooter is operated in this direction, which is the same driving method as that in the forward movement. The only difference is that the scooter is in a state of driving after waiting.

Meanwhile, the human body detection sensor 17 is installed on the handle 12 of the controller 10, or the scooter is operated by pressing an operation switch (not shown) for operating a control command between the controller 10 and the scooter, and when the controller 10 is removed from the user, the scooter is automatically stopped so that the scooter does not malfunction.

On the other hand, in another embodiment, a small throttle (joystick, not shown) is mounted on the outside of the controller 10 to rotate the controller 10 directly to the left or right and drive the throttle to the left and right, thereby rotating the scooter to the left or right accordingly. In the case where the test result is rotated, the throttle valve can also be safely controlled.

That is, the controller 10 is a controller in which a sensor unit and a throttle valve type are mixed, and the sensor unit is responsible for driving and stopping, and the throttle valve is responsible for left and right rotation.

At this time, when the throttle is used to rotate left or right, the steering angle of the scooter is 60 degrees or less on each side, and therefore sufficiently fine rotation control can be performed even if the throttle is used.

On the other hand, it can be used by incorporating the controller 10 in a skateboard glove, a wrist protector, a knee protector, etc., and the controller 10 can be applied to all electronic products using a wireless controller.

As shown in fig. 1 to 2, the panel body 20 is a rectangular plate-shaped body, and may be designed in various shapes of a square, a circle, an oval, etc., in addition to a rectangular shape, and the panel body 20 is formed of various materials such as wood, plastic materials, and metal materials.

At this time, the plate body 20 has pressure sensors 21, the pressure sensors 21 are installed at portions where both feet of the user are placed to determine whether the user is on the scooter, and when the pressure sensors 21 detect with a load that the user has got on the scooter, a signal is transmitted to the control device 80, and the control device 80 releases the lock, so that the board can be driven to prepare for driving.

And, by moving the rider's foot on the pressure sensor toward the center of the scooter (outside of the pressure sensor) or putting the next foot, the scooter will turn off the power and stop automatically, and has a function of safe riding in addition to the human body detection sensor of the controller, the acceleration sensor, the gyro sensor, the battery position and the controller not operating when put on the floor.

As shown in fig. 1 to 2 and 6 to 10, the front wheel unit 30 and the rear wheel unit 40, which are formed as a pair, are connected to the lower side of the board 20 by a scooter 50, the front wheel unit 30 is formed at the front of the scooter, and the rear wheel unit 40 is formed at the rear of the scooter.

At this time, as shown in fig. 10, the front wheel section 30 and the rear wheel section 40 are respectively connected to a first electric motor 60 to change the direction by the first electric motor 60, the first electric motor 60 is attached to or built in the lower side of the cart 50 or the board body 20, a drive lever 61 connected to a rotation shaft of the first electric motor 60 is connected to the pair of front wheel sections 30 and the pair of rear wheel sections 40, and the directions of the front wheel section 30 and the rear wheel section 40 are switched according to the rotation direction of the first electric motor 60. In this case, the first motor 60 is a motor that adjusts an angle by a sub motor, PID control, or the like.

That is, the drive lever 61 of the first motor 60 is connected to the pair of

wheel portions

30, 40, directly changes the direction of the

wheel portions

30, 40 in the same manner as the principle of changing the wheels of the vehicle, and the drive lever 61 of the first motor 60 is connected to the horizontal axis of the cart 50, and rotates the horizontal axis left and right to change the direction of the

wheel portions

30, 40. At this time, since the structure and principle of the wheel steering are well known technologies, a separate structure, construction and principle are not described. At this time, the first electric motor 60 is mounted only on the front wheel section 30 so as to be able to easily change the direction.

As shown in fig. 1 to 2 and 11, the mounting position of the second motor 70 varies depending on whether the scooter is of a two-wheel drive type or a four-wheel drive type, and is mounted only on the pair of rear wheel portions 40 if the scooter is of a two-wheel drive type, and is mounted on the front wheel portion 30 and the rear wheel portion 40 to rotate or stop each

wheel portion

30, 40 independently if the scooter is of a four-wheel drive type.

At this time, the second motor 70 may be a wheel hub motor, which is a motor manufactured to rotate the outside of the wheel on the same principle as the motor of the washing machine, or a truck-mounted motor, and the structure, construction and operation principle will not be described since it is the same as the existing wheel hub motor.

As shown in fig. 1 to 2, the control device 80 is mounted on the panel body 20 to receive a signal from the pressure sensor 21 or the sensor unit 11 of the controller 10, and controls the first motor 60 and the second motor 70 according to the signal from the sensor unit 11. At this time, the control device 80 corresponds to a microcomputer in which a microprogram is set.

At this time, as described above, the control device 80 is a processor that receives a signal from the pressure sensor 21 and prepares for driving to enable the scooter to be driven, and the controller 10 controls the first and

second motors

60 and 70 according to the control by transmitting signals to the first and

second motors

60 and 70 according to the direction instructed by the controller 10, and controls the rotation speed and the rotation direction of the first and

second motors

60 and 70 when the switch is operated according to the running mode of the controller 10.

On the other hand, a battery unit 90 for supplying power to the first motor 60, the second motor 70 and the control device 80 is further installed at the lower side of the board body 20, and the battery unit 90 is formed to be chargeable and detachable.

On the other hand, the connection between the controller and the control device may be a wireless connection, such as bluetooth, Wi-Fi, Zigbee, RF, etc., and the data transmission from the controller to the control device is a command from the rider, a command for sending the scooter status information that the rider needs to know, etc., and the data transmission from the control device side to the controller is the scooter status information, such as remaining battery capacity, current scooter speed and travel distance information.

On the other hand, the scooter of the present invention is easy to rotate, and when the first motors inside and outside rotate, the lengths of the arcs drawn by the inner wheel and the outer wheel are different, thereby preventing smooth rotation, and when the first motors inside and outside rotate, the outer wheel cannot follow the speed of the inner wheel, so that the rotation angle of the front wheel is measured according to the rotation command of the rider, and the matched rotation radius is obtained, and after the difference between the moving distances of the inner wheel and the outer wheel is calculated, the rotation number of the outer wheel is controlled to be increased or decreased, thereby ensuring safe, smooth and easy rotation. At this point, the same algorithm is applied for left or right turns, and the effect of the automotive differential is resolved by the program.
