[0002] Electric scooters are a type of transportation that uses a motor hub drive or belt drive. They are lightweight, flexible, compact and portable. Electric scooters are generally used for short-distance commuting. However, because the front of an electric scooter is relatively narrow, there are no rearview mirrors to observe vehicles or pedestrians behind it.

[0003] When riders use electric scooters, if they are wearing helmets or have loose hair, blind spots may occur when changing lanes in situations with insufficient light or heavy traffic and pedestrians, potentially leading to collisions with pedestrians. This is a shortcoming. Therefore, a function that uses radar sensing and emits warning lights (such as red / yellow / green lights, or one or more warning colors) to remind riders to change lanes should be added to the narrow handlebar area. This function should monitor the distance between the scooter and vehicles or pedestrians behind it, and automatically trigger a light warning when the distance is too close or when changing lanes, thus improving lane-changing safety.

[0004] Existing electric scooter riders often lack lane change warning devices that detect vehicles or pedestrians behind them, which are designed to protect the narrow front of the scooter from collisions. To address this, this application proposes an electric scooter lane change warning device. Utility Model Content
