Description

Technical Field

[0001] The present invention relates to the technical field of electric motors, and in particular to a glare structure, a hub motor using the structure, and an electric balancing vehicle using the hub motor, which are suitable for electric balancing vehicles, toy vehicles, or other sports tools. Background Art

[0002] Electric balancing scooters are also called somatosensory scooters, thinking scooters, and position-control scooters. There are two main types of scooters on the market: one-wheeled and two-wheeled. The operating principle is based on a basic principle called "dynamic stabilization". It uses the gyroscope and accelerometer inside the scooter to detect changes in the scooter's posture, and uses a servo control system to accurately control the scooter's posture.

[0003] The electric balance car is a new type of green and environmentally friendly sports tool used by modern people as a means of transportation, leisure and entertainment.

[0004] At present, electric balance scooters usually use wheel hub motors to drive the operation of the electric balance scooters, and the tires are attached to the wheels of the wheel hub motors. At this time, the tires not only bear the weight of the entire vehicle, but also play the role of shock absorption and buffering. It is the most important part of the entire vehicle, and has a direct impact on the driving performance, passability, environmental protection, comfort and safety of the electric balance scooter. In addition, with the popularity of electric balance scooters, electric balance scooters are especially popular among teenagers. Teenagers often use electric balance scooters as a tool for sports and entertainment, so the safety of electric balance scooters is particularly prominent.

[0005] When using an electric balancing scooter at night, the moving target is not so conspicuous, and it is not enough for surrounding vehicles and pedestrians to find the moving balancing scooter as soon as possible, which often leads to safety hazards when the electric balancing scooter is driven at night. Therefore, designers have designed a variety of light strip decorations on the wheels to show the moving balancing scooter. For example, Chinese patent CN207842526U discloses a scooter and its wheels, and the wheels have a luminous function. However, its luminous installation structure is multi-

[0006] The stacking of layers, the luminous effect form is single and the installation structure is complicated, which only shows the existence of light, and cannot prompt or show the light or light that can penetrate the night, and thus cannot well detect the running electric balance car from a distance.
