Smooth obstacle crossing walking mechanism

Abstract

The invention belongs to the technical field of walking mechanisms, and provides a smooth obstacle crossing walking mechanism which can maintain small friction loss and high efficiency while providing high smooth obstacle crossing capacity and is suitable for most daily use situations. The smooth obstacle crossing walking mechanism comprises a driving wheel and a contact wheel. The driving wheel is small in diameter, the contact wheel is large in diameter, the driving wheel can autonomously rotate around the axis of the driving wheel under the action of driving force, the driving wheel is compressed with the inner edge of the contact wheel under the action of gravity, the contact wheel makes contact with the ground, and when the driving wheel actively rotates, the driving wheel walks along the inner edge of the contact wheel under the action of friction force between the driving wheel and the contact wheel. The contact wheel rolls forwards under the action of gravity and friction force of the driving wheel, and walking of the smooth obstacle crossing walking mechanism is achieved.

Description

technical field [0001] The invention belongs to the technical field of walking mechanisms, in particular to a smooth obstacle-surmounting walking mechanism. Background technique [0002] Currently, there are two main types of walking mechanisms on the market, wheeled and tracked. Among them, the wheeled walking mechanism is the mainstream, such as four-wheel vehicles, four-wheel electric vehicles, two-wheel balance vehicles, two-wheel electric vehicles and so on. The advantage of the wheel-type walking mechanism is that it has low friction loss with the ground and high efficiency. It is suitable for driving on a relatively flat road. However, when encountering obstacles such as steps, the performance is not ideal. Its obstacle-surmounting ability depends on the wheel diameter and driving ability. It is easy to cause a sudden change in height when crossing obstacles. For example, when going up and down steps, the sudden change in height makes the riding experience poor. The...

The crawler-type walking mechanism has a strong ability to overcome obstacles, but this mechanism has a large friction force with the ground and the efficiency is very low, so it is not suitable for daily use, and the crawler-type walking mechanism is also easy to cause a sudden change in height when it overcomes obstacles , For example, when the crawler-type walking mechanism starts to go down the steps from the flat ground, or when it reaches the top of the steps and starts to walk on the flat ground, there will be a sudden change in height, and the riding experience is very poor.
