Personal transportation vehicle

Abstract

The invention provides a personal transportation vehicle comprising a chassis, a support structure, an auxiliary wheel supporting arm, a support structure actuator and an auxiliary wheel actuator. Wheels are arranged on two sides of the chassis; the support structure is pivoted to the chassis to form a parallel four-link mechanism; the top of the auxiliary wheel supporting arm is pivoted to the support structure, and the bottom is provided with an auxiliary wheel; the support structure actuator is arranged on the chassis and is connected to the support structure, and the auxiliary wheel actuator is arranged on the support structure and is connected to the auxiliary wheel supporting arm; during usage, the support structure actuator and the auxiliary wheel actuator drive the support structure and the auxiliary wheel supporting arm, respectively, to move so as to change the positions of moving wheels, and a two wheel grounding balance mode and a multiple wheel grounding balance mode are formed respectively. When the driving state of the vehicle is not stable, the stable state of three wheel grounding driving can be adopted, and safety and stability are high.

Description

technical field [0001] The present invention relates to a transportation vehicle, in particular to a two-wheeled personal transportation vehicle. Background technique [0002] In addition to general motorcycles and bicycles, as far as personal transportation vehicles currently on the market are concerned, in order to achieve static stability, at least three ground contact support points will be used as the basic structure of the transportation vehicle. The area where the driver rides is not large, but in order to achieve a certain degree of stability and safety, the wheelbase still must have a certain length, which makes the volume of this transport vehicle usually long, large and The relatively heavy problem makes it quite inconvenient for this kind of transportation vehicle to be used as a means of transportation in today's densely populated urban areas. Under the trend of continuous and rapid urbanization, this problem will become increasingly serious. [0003] In recent...

Problems solved by technology

However, it can be found from its content that the method of changing the center of gravity of the vehicle is mainly through the use of two sets of linear telescopic devices, both are indispensable, and the changing process has a fixed sequence condition

In addition, because the driving wheels will leave the ground first and then touch the ground during the transformation process, it can be seen that the transformation process can only exist in a stationary state, otherwise the vehicle will become uncontrollable, so the functionality and restricted

[0006] The vehicle structure of the above-mentioned adjustable wheels maintains at least three wheels on the main ground contact elements. In order to achieve a stable and safe state, its center of gravity must always remain within the supporting polygon formed by the three wheels. The problem of long volume. General personal transport tools such as wheelchairs are not only used in open outdoor spaces, but also often used in indoor environments with limited space. Once the volume is too large and too long, the flexibility and maneuverability in the space Therefore, the carrier structure of the above-mentioned adjustable wheels has lost the advantage of taking up a small volume, so this kind of personal transportation carrier in the prior art still needs to be further improved
