Electric roller skate based on inline skating structure

Abstract

The invention provides an electric roller skate based on an inline skating structure. The electric roller skate comprises a structure bracket and a plurality of skate wheels which are connected to the structure bracket by virtue of shafts and are distributed in a linear mode, wherein three holding grooves are formed in the structure bracket; the skate wheels are composed of round hub motors and skate wheel tires covering the outer circumferences of the hub motors; control circuits, electronic speed controllers and batteries are respectively fixedly arranged inside the three holding grooves; the control circuits are connected to the electronic speed controllers, the hub motors and battery circuits; and the hub motors comprise permanent-magnet brushless DC motors. According to the electric roller skate disclosed by the invention, the control circuits and the electronic speed controllers are arranged inside the structure bracket of the roller skate; the control circuits can directly pass through the electronic speed controllers and the hub motors inside the roller skate; power of the roller skate is supplied from the hub motors instead of from the feet of a user; and by virtue of the inline skating structures of the skate wheels, the roller skate is conducive to adapting to complex urban roads.

Description

technical field [0001] The invention relates to the field of roller skates, in particular to an electric roller skate based on an inline wheel structure. Background technique [0002] With the deteriorating environment and the continuously improving quality of life, roller skates, which are more environmentally friendly, have received extensive attention as a means of transportation. However, ordinary roller skates still need manpower to slide to generate forward kinetic energy, and this kinetic energy can only last for a short time. Therefore, roller skates made of electric instead of manpower are called new research topics. [0003] Currently, the only electric roller skates on the market have a top speed of 16km / h, a climbing ability of 5°-8°, a battery life of about 45 minutes, and a maximum load-bearing capacity of 120Kg. Each foot is driven by two 50w DC motors, the control method is to use the heel pressure to accelerate, and the rear Bluetooth module is used to bala...

Problems solved by technology

[0004] This electric roller skates scheme has the following disadvantages. Disadvantage 1: Poor adaptability. In view of its special structural design, existing electric roller skates can only run on flat roads and cannot adapt to complex and changeable urban roads; Disadvantage 2 : Slow speed, the existing electric roller skates can only reach a running speed of 16km / h, and need to press the heel back to accelerate; Disadvantage 3: Poor climbing performance, and the climbing ability of 5°-8° is too limited , the slope of sidewalks and inner streets in the city may reach 20° at most, so it is necessary to invent an electric roller skate that can adapt to complex and changeable urban roads, and has a faster speed without requiring manpower to give it a starting speed
