Problems solved by technology
Therefore, when the voltage of the battery 16 is insufficient or oversaturated, the brightness of the brake light 451 is often insufficient or too bright, which in turn causes improper changes in the brightness of the brake light 451 flickering under the same driving conditions.
In addition, when the electric scooter A climbs a slope, most of the electric energy of the battery 16 will be used for the climbing of the electric scooter A, thus causing an instantaneous voltage drop of the battery 16, which will also cause the brightness of the brake light 451 to flicker improperly. Changes, the existing electric scooter brake light control system 4 needs to be improved

The invention discloses a stoplight control device of an electric scooter. The stoplight control device at least comprises a protection circuit, a voltage stabilizing circuit, a driving circuit, a central processing unit, a headlamp switch and a motor controller. The stoplight control device is characterized by comprising a voltage division circuit which is electrically connected between the central processing unit and the protection circuit, the central processing unit senses an output voltage value of a battery; when the headlamp switch is touched or the motor controller sends a motor braking signal, the central processing unit can output an appropriate conducting signal in a pulse width modulation (PWM) way by matching with the sensed actual voltage value of the battery, therefore, a stoplight can acquire an appropriate working voltage so that the stoplight can send the brightness which is stable and can match with the actual traveling state.
Description
technical field [0001] The invention relates to a brake light control device for an electric scooter, in particular to a brake light control device for an electric scooter that can obtain a stable working voltage and thus have stable brightness for the brake light of the electric scooter. Background technique [0002] Nowadays, it is becoming more and more common for the elderly and disabled to use electric scooters. Because of the degeneration of physiological functions, the use of electric scooters is in line with their needs. From the perspective of industrial development, in terms of growth rate, the market has grown extremely fast in recent years due to the great leaps in product functions and technologies of electric scooters and the rise of silver-haired consumption. In the future, the global market will also grow at an extremely fast rate. It can be seen that the value of its products has been greatly valued by advanced countries. [0003] An electric scooter is a k...
