Description
Technical field
The application is related to balance car safety testing field, more particularly to a kind of balance car riding safety test machine.
Background technology
In recent years, a kind of new product development with computer controlled automatic anterior-posterior balance is quite rapid, and the product has a variety of
Type, it can simply be divided into three generation products.
First generation product is referred to as thinking car, left and right two-wheel bi-motor band course changing control handle；Second generation product is referred to as electronic
Wheelbarrow or single wheel balance car, by single drive and control of electric machine；Third generation product is balance car popular in the market, again
Claiming electrodynamic balance car, electrodynamic balance swing car or two-wheel, balance car is by left and right two-wheel motion sensing control direction without bar human-computer interaction car.
All three generation products may serve to a kind of new green environment protection product as walking-replacing tool, amusement and recreation.
Its operation principles is mainly built upon one kind and is referred to as in the general principle of " dynamic stability ", using vehicle body gyroscope and
Acceleration transducer, to detect the change of vehicle body attitude, and servo-control system is utilized, accurately motor carries out corresponding
Adjustment, to keep the balance of system.
