It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.

The embodiment provides a portable scooter and a control method thereof, as shown in fig. 1-7, comprising a scooter body 100 and two wheels 200 with hub motors, wherein the scooter body 100 is provided with two pedal areas 110, the two pedal areas 110 are respectively positioned in front of and behind the two wheels 200, and the scooter body 100 can swing back and forth and swing left and right; the scooter is provided with a controller connected with the hub motor and an angle sensor connected with the controller.

The scooter is provided with a battery for supplying power to the scooter. Referring to fig. 4, the right and left sides of the drawing are the front and the rear of the scooter, respectively, when the scooter body 100 swings forwards, i.e. the front end of the scooter body 100 swings downwards, and the rear end of the scooter body 100 swings upwards, so as to control the scooter to move forwards. Referring to the perspective of fig. 5, the left and right sides of the figure are the left and right sides of the scooter, respectively, and when the scooter body 100 swings left or right, the scooter is controlled to turn left or right. As shown in fig. 6, the vehicle body 100 swings to the left, that is, the left end of the vehicle body 100 swings downward, and the right end of the vehicle body 100 swings upward. In this embodiment, the swing of the vehicle body 100 is the swing of the whole vehicle body 100, and in other alternative embodiments, the swing of the vehicle body 100 may also be the swing of a partial structure on the vehicle body 100.

The angle sensor may be a gyroscope mounted on the vehicle body 100, the gyroscope may detect swing angles of the vehicle body 100 in four directions, i.e., front, rear, left, and right directions, and transmit angle swing angle information to the controller, and the controller controls the in-wheel motor to perform corresponding driving actions. In other alternative embodiments, the angle sensor may also be an infrared sensor or an ultrasonic sensor to detect the distance between the corresponding position of the vehicle body 100 and the ground, so as to detect the swing angle. The angle sensor may be a pressure sensor, for example, the vehicle body 100 may be divided into a swinging member and a fixed member, the fixed member may be provided with the pressure sensor, a spring may be provided between the pressure sensor and the swinging member, and the larger the swinging angle of the swinging member is, the higher the pressure applied to the spring is, so that the swinging angle of the vehicle body 100 may be determined based on the pressure detected by the pressure sensor. The angle sensor may also be a magnetic field sensor, and the magnetic field sensor detects a change in a magnetic field of a corresponding magnet on the scooter to determine the swing angle of the scooter body 100.

The straight line through the back and forth swing control scooter of automobile body 100 traveles, controls turning to about the scooter through the horizontal hunting of automobile body 100, and the scooter just need not to set up the handle like this, reduces scooter occupation space, improves the portability of scooter.

When the included angle between the scooter body 100 and the horizontal plane is more than or equal to a preset angle, controlling the scooter to enter a dormant state; as shown in fig. 3, when presetting angle a to 10, then automobile body 100 and horizontal plane contained angle more than or equal to 10 when, automobile body 100 inclination is great, and this state appears at the in-process of traveling, can the scooter appear out of control, makes the scooter get into the security that the dormant state can improve the scooter. When the scooter was placed naturally, automobile body 100 one end contacted ground avoided the scooter directly to get into the state of traveling during the start, further improved the security that the scooter used.

When the included angle between the scooter body 100 and the horizontal plane is smaller than the preset angle, the scooter is controlled to enter the working state.

The two pedal areas 110 are respectively positioned in front of and behind the two wheels 200, so that the two wheels 200 are arranged at the position between the two pedal areas 110 or the junction position of the two pedal areas 110, and the two wheels 200 are arranged in the width direction of the scooter body 100, so that the two wheels 200 can be close to each other, the steering radius of the scooter is favorably reduced, and the steering flexibility of the scooter is improved. The two wheels 200 can rotate around the same axis, so that the steering of the scooter can be realized by controlling the difference of the rotating speeds of the two wheels 200. In this embodiment, the distance between the two wheels 200 is greater than the width of the scooter body 100, which is beneficial to improving the driving stability of the scooter.
