Description

Technical Field

[0001] The invention relates to the technical field of electric skateboards, in particular to an electric four-wheel skateboard. Background Art

[0002] An electric skateboard is a skateboard equipped with an electric drive mechanism, which is used to replace the traditional human-powered skateboard. It is powered by an electric motor, which enables the skateboard to move automatically without the need for the rider to pedal or push. Electric skateboards can be used as a means of transportation for short-distance travel in the city. It is portable and can be moved quickly in the city, which is convenient for commuting, shopping, social activities, etc. Compared with cars and bicycles, electric skateboards are more flexible and convenient and can travel through crowded traffic.

[0003] Traditional electric skateboards may experience greater bumps and shaking during driving, which is mainly due to the lack of an effective wheel shock-absorbing mechanism. The lack of a wheel shock-absorbing mechanism makes it difficult for the skateboard to absorb unevenness and vibrations on the road, affecting the user's riding experience and driving stability. In addition, due to the lack of a fixed wheel shock-absorbing mechanism, the rolling wheel is subjected to greater force, which can easily lead to wear and damage to components, which means that more frequent repairs and replacement of components are required, increasing the cost and trouble of use. In addition, the batteries in traditional electric skateboards are often affected by vibrations, which may damage the internal structure and active substances of the battery, accelerate the aging and damage of the battery, and shorten its service life. In addition, the control method of traditional electric skateboards is usually relatively simple, which makes it difficult to meet the needs of riders in different road conditions and environments. It lacks the ability to flexibly adjust the sliding speed and direction, limiting the rider's control and experience. Summary of the invention
