Abstract

The invention discloses an intelligent stair climbing wheelchair with an effect of automatic distance measurement. The wheelchair comprises a travelling and climbing mechanism, a wheelchair rack, a seat, an automatic mass center regulation mechanism, and a battery pack, wherein the seat is arranged inside the wheelchair rack due to a seat suspension mechanism, and the seat suspension mechanism is connected with the wheelchair rack through a spherical hinge; the travelling and climbing mechanism comprises a star wheel mechanism and an automatic mass center regulation support; the star wheel structure is connected with the wheelchair rack by virtue of the mass center automatic regulation support; the star wheel structure has three star wheel expansion links which are uniformly distributed in circumference; the free end of each star wheel expansion link is provided with a star wheel, a servo motor is used for driving the star wheel expansion links to rotate around a transmission shaft, and star wheels rotate freely around an assembly shaft. When the intelligent stair climbing wheelchair is on a flat ground, two star wheels are contacted with the ground; when the wheelchair is used for climbing stairs, the servo motor is used for driving the star wheel expansion links to rotate according to a control signal sent by a control system processor, so that stair climbing is realized.

Description

technical field [0001] The invention relates to the technical field of wheelchairs, in particular to an intelligent stair-climbing wheelchair with automatic distance measurement. Background technique [0002] Wheelchairs are an important life aid for people with limited mobility. For the elderly, people with leg disabilities or people who cannot walk independently temporarily, wheelchairs have brought great convenience to their lives. However, during the use of wheelchairs, stairs and steps cannot be climbed, and barrier-free passages are not provided in many occasions. Therefore, wheelchairs with the function of climbing stairs have important practical value. [0003] In order to realize the stair-climbing function, the existing stair-climbing wheelchairs mainly include continuous type and intermittent type; the main feature of the continuous stair-climbing wheelchair is that there is a group of supporting devices in the process of climbing stairs, and the continuous moveme...
