Problems solved by technology
[0004] In recent years, the concept of "electric skateboard" has frequently appeared in school science and technology competitions and even in the market. Most electric skateboards use electronic brakes, but electronic brakes will inevitably cause signal loss, poor wire contact and other factors, and there are some problems in the use of electric skateboards. potential safety hazard

The invention relates to an electrically driven skateboard, in particular to a micro-hub oil pressure braking system of the electrically driven skateboard. The micro-hub oil pressure braking system isprovided with a load-bearing wheel with a disc brake mechanism, trucks, a micro-hub oil pressure braking mechanism, a pedal braking power mechanism and an oil tube; the load-bearing wheel with the disc brake mechanism is provided with a pair of nuts, a pair of outer bearings, a pair of outer wheel covers, a pair of skateboard outer wheels, a pair of load-bearing steel rings with braking discs, apair of inner wheel covers and a pair of inner bearings; the micro-hub oil pressure braking mechanism is provided with a pair of symmetrical brake pads, a pair of symmetrical brake pad fixing frames,a pair of symmetrical small piston sealing covers, a pair of symmetrical small pistons and a pair of symmetrical small oil brake cylinder bodies; and the pedal braking power mechanism is provided witha piston cap, a return spring, a piston sealing cover, a power piston rod and a large piston oil cylinder. External braking devices are embedded in the wheels of the skateboard, the front truck is adopted as a centrally-through oil way, and the braking devices are concise in appearance and light; and mechanical oil pressure braking is adopted, thus the braking efficiency is higher, and the safetyfactor is higher.
Description
technical field [0001] The invention relates to an electric drive skateboard, in particular to a miniature hub hydraulic brake system for an electric drive skateboard using an embedded hub hydraulic brake as a braking method. Background technique [0002] Skateboarding is an extreme sport that is deeply loved by young people at home and abroad. The International Skateboarding Association (IASC) organizes World Skateboarding Day and sets World Skateboarding Day as June 21 every year. Skateboarding has become one of the coolest sports on the planet today. Skateboards can be divided into two categories: (1) trick skateboards; (2) street-style skateboards. The technical content of figure action skateboards far exceeds that of street-style skateboards. The street-style skateboard is not limited by the venue, and is favored by skaters in daily life. However, in daily life, many street-style skateboarders do not wear protective equipment such as helmets and gloves, and the result...
