Problems solved by technology

Under this situation, the power of the outer hub motor is insufficient, resulting in a large overall rotation radius of the skateboard, while the inner hub motor is forced to run at a low speed due to the increased friction between the inner wheel and the ground. On the one hand, the energy is lost in heat, and on the other On the one hand, the hub motor itself has been greatly damaged in the long run

Embodiment Construction

[0037] The present invention will be further explained below in conjunction with the accompanying drawings.

[0038] A rear-wheel-driven electric four-wheel skateboard includes a skateboard body and four runners. Hub motors are installed on the two runners at the rear of the skateboard body, and Hall sensors for detecting rotational speed are installed on the hub motors. Such as figure 1 As shown, four double-arm bridge pressure detectors are fixed on the surface of the main body of the skateboard, and each double-arm bridge pressure detector includes two bridge pressure detection circuits composed of strain gauges. The arm bridge pressure detectors are arranged side by side at the front of the board, and the other two double-arm bridge pressure detectors are arranged side by side at the rear of the board, and a gyroscope is installed at the geometric center of the board. sensor. A controller is installed on the main body of the skateboard, and the controller is connected to...

Abstract

The invention discloses an electric four-wheel skateboard with a differential steering control function. The steering intention of a user is judged according to the roll angle value output by a gyroscope sensor; the control target of a differential steering control model is that the rotating speed of a hub motor steered to the outer side is larger than the rotating speed of a hub motor steered tothe inner side, and the rotating speed difference value of the hub motor steered to the outer side and the hub motor steered to the inner side is positively correlated with the roll angle value. Differential steering control is added, so that the turning radius is reduced, the safety and convenience are improved, the motor loss caused by the fact that the hub motors cannot reach a rated rotating speed is reduced, and the overall service life of a product is prolonged.

Description

technical field [0001] The invention relates to an electric four-wheel skateboard with differential steering control. Background technique [0002] Common electric slider control methods on the market can be divided into handheld remote control and center of gravity control, and can be divided into external belt motor and hub motor according to the driving method. For the existing center of gravity control type electric skateboard, when the user operates the electric steering, it needs to be controlled by tilting left or right. At this time, the skateboard is no longer parallel to the ground, and there is a certain tilt angle. The two hub motors are divided into steering inner and Turning to the two motors on the outside, due to the different turning radii, the two hub motors should not have the same speed, and therefore should not have the same power output. Under this situation, the power of the outer hub motor is insufficient, resulting in a large overall rotation radius...
