Steering device of resistance two-wheel balance vehicle based on Hall encoder

Abstract

The invention relates to a resistance type Segway steering device based on a Hall encoder. The resistance type Segway steering device comprises a brake lever, a brake wire, a signal conversion device and a handrail, wherein the signal conversion device comprises a displacement rotation conversion mechanism and a Hall encoder; the displacement rotation conversion mechanism comprises parallel connection columns, and each connection column is driven by the brake wire and moves in a guide slot and has a toothed surface; a gear in occlusion with two connection columns respectively is arranged between the two connection columns; a powerful magnet is embedded in the gear; the detection axle center of the Hall encoder is coaxial with the gear; and the Hall encoder receives the rotation displacement of the gear and converts into an electric signal which is sent to a controller. In the invention, by adopting a brake wire structure, the recovery force is relatively low, the operation is easy, and the requirements on a recovery spring are reduced; since the Hall encoder measures a steering signal, the steering safety can be improved; the structure is simplified by the non-contact property of the Hall encoder; and through a resistance type steering control method, the operability of a turning mechanism is enhanced.

Description

technical field [0001] The invention relates to a steering device of a balance car, in particular to a resistance type two-wheel balance car steering device based on a Hall encoder. Background technique [0002] The two-wheel balance car is a new type of electric vehicle developed in recent years. At present, it is mainly used for short-distance travel, so it is also called a scooter. [0003] The steering device of the balance car is the core component of the communication between people and the balance car. The basic principle of the steering device of the balance car is to convert the displacement into an electrical signal; then, the electrical signal is given to the controller; the controller according to the prior design A good rule is to adjust the voltage of the two wheels; finally, the adjusted voltage acts on the two wheels, causing the relative rotational displacement of the two wheels to realize the steering. [0004] At present, the basic composition of the ste...
