Description

Transport device that can be used with electric unicycle

Technical field

The invention relates to an electric unicycle peripheral device, in particular to a transport device which can be used with an electric unicycle.

Background technique

The electric unicycle is an electric-driven, self-balancing personal transportation vehicle. It is a kind of urban transportation. It is a new vehicle that has never been seen before. It is also called a physical car and a thinking car. In personal transportation, work inspections, indoor venues, golf carts, police patrols, exhibition patrols, large venue staff transportation, tourism and entertainment, and car loading;

Today, with the rapid development of society, traffic congestion has become a common phenomenon in many large and medium-sized cities. A convenient electric unicycle will allow users to enjoy the ease and happiness of shuttle bus and the speed of commuting to and from work;

However, the electric unicycle has a hard injury, that is, the learning cost is too high. The balance principle is similar to the bicycle in the circus. During the movement of the electric unicycle, the human body leans forward, and the electric unicycle accelerates to run, balance, and the human body. Tilting backwards, the electric unicycle decelerates and maintains balance. However, the balance between the left and right of the electric unicycle is controlled by the user himself. An ordinary user, to achieve such a balance, is very very difficult, at least learning The time is up to 6 or 7 hours to tens of hours, and the process of learning is very hard. During the practice, due to the imbalance, the human body will have a self-protection response, and the whole body muscles will be tight. This is very Consuming physical strength;

Moreover, if the balance is not good enough, such as a part of the people who are not riding bicycles, it may be difficult to learn an electric unicycle;

Last year, this unicycle sold millions of units nationwide. However, there are very few people who see it on the road. There is almost no one. The important reason is that the cost of learning is too high, it is not good to learn, it will not be learned, it will not be on the road or there will be very on the road. Big security risks;

Such high learning costs directly result in waste of resources, low utilization rate, and the sales of electric unicycles will be greatly discounted as time goes by.

Summary of the invention

The object of the present invention is to overcome the above-mentioned deficiencies in the prior art, and to provide an electric unicycle that is more portable, makes the electric unicycle easier to drive, adds more practical functions, and improves the utilization rate of the electric unicycle. A transport device that transitions between multiple public transportation vehicles.

In order to achieve the above object, the present invention provides the following technical solutions:

A transport device for use with an electric unicycle for use with an electric unicycle consisting of an outer casing and a single wheel mounted within the outer casing, the single wheel being rotatable within the outer casing and partially exposing the outer casing For contact with the ground, the transport device comprises:

a skeleton on which a link mechanism and a storage device for the load are disposed;

a wheel having a number of wheels equal to or greater than two for supporting a skeleton movement, disposed on both sides of the skeleton, and connected to the link mechanism, wherein the plurality of wheels are capable of synchronous deflection;
