Embodiment 1

[0026] see figure 1 , figure 2 , a handleless two-wheel self-balancing electric vehicle that controls direction with the center of gravity, the two-wheel self-balancing electric vehicle includes an electric vehicle body, and the electric vehicle body includes a vehicle frame 16 arranged inside the electric vehicle and a The outer casing 4, which is at the outermost side of the vehicle, is used to support various parts of the vehicle body, and at the same time isolate the operator from the motor to prevent accidents; the vehicle frame 16 includes a left wheel hub frame and a right The hub frame, and the connecting shaft 9 arranged between the left hub frame and the right hub frame, the connecting shaft 9 is used to connect the left hub frame and the right hub frame, and the left hub Both the vehicle frame and the right wheel hub frame are provided with pedals 1, tire components are provided on both sides of the electric vehicle body, and a control circuit 12 is arranged in th...

Embodiment 2

[0028] see figure 1 , figure 2 , image 3 , as an improvement of the present invention, the control circuit includes a microprocessor, a power module, a temperature sensor, a current sensor, a Hall sensor, an attitude detection unit, a strain gauge, a motor drive circuit, a Bluetooth module, a wireless remote control module, a human Machine interaction module, the power module, temperature sensor, current sensor, Hall sensor, attitude detection unit, strain gauge, motor drive circuit, bluetooth module, wireless remote control module, human-computer interaction module are all connected to the microprocessor, the The attitude detection unit is composed of a gyroscope and an accelerometer, which is used to detect the attitude of the car body relative to the ground, including the left attitude detection unit and the right attitude detection unit, which are respectively located under the left wheel frame and the right wheel frame , and fixed on the frame. In this technical solu...

Embodiment 3

[0030] see figure 1 , figure 2 , as an improvement of the present invention, the tire component includes an in-wheel motor 6, a tire 17 arranged outside the in-wheel motor, and a protective cover 18 arranged above the tire, and the protective cover 18 is provided with an anti-collision sticker 5 . The hub motors are one on the left and one on the left, which are used to provide power to the vehicle. The tires 17 are on the outside of the hub motor 6, which can protect the motors and have a shock-absorbing effect, and can achieve a better riding experience; the technical solution Among them, the in-wheel motor 6 is a single-axis design, with only one fixed shaft, which is locked on the frame through a pressure block. The single-axis design reduces the weight of the motor and simplifies the installation steps; the outside of the in-wheel motor is covered with tires, and the tires are 17 In order to avoid inflating rubber tires, the inflation process is omitted, and safety haz...

Abstract

The invention relates to a double-wheel self-balancing electric vehicle without a handle using the gravity center to control direction and a control method thereof. The double-wheel self-balancing electric vehicle is characterized by comprising an electric vehicle body, the electric vehicle body comprises a frame arranged in the electric vehicle and a shell arranged outside the electric vehicle, the frame comprises a left hub frame, a right hub frame and a connecting shaft arranged between the left hub frame and the right hub frame, the connecting shaft is used for connecting the left hub frame with the right hub frame, each of the left hub frame and right hub frame is provided with a pedal plate, a tire component is arranged at each of two sides of the electric vehicle body, a control circuit is arranged in the electric vehicle body, and the control circuit controls the advancing and reversing of the vehicle through the motor through detecting the front and back gravity center change of an operator.

Description

technical field [0001] The invention relates to an electric vehicle, in particular to a handleless two-wheel self-balancing electric vehicle whose direction is controlled by a center of gravity, and belongs to the technical field of self-balancing electric vehicles. Background technique [0002] Two-wheel self-balancing electric vehicles have appeared in various transportation occasions, but traditional two-wheel self-balancing electric vehicles require the rider to control the front and rear balance with the center of gravity, and control the steering with the handle. Cause the car body structure to be complicated, and volume is bigger, and portability reduces greatly. [0003] In order to solve this technical problem, those skilled in the art are also constantly trying. Most of the new self-balancing electric vehicles on the market are relatively complicated, costly, and troublesome to disassemble and maintain. Therefore, a new technical solution is urgently needed to solv...
